The present disclosure disclosed a method of determining a buffer status report (BSR). The method comprises obtaining, by a user equipment (UE) from a buffer, data item to be sent; determining, by the UE, a size of the data item to be sent; determining, by the UE, a minimum number of required logical channel groups (LCGs) based on the data item to be sent; and determining, by the UE, at least one BSR with flexible length based on the size of the data item to be sent and the minimum number of the required LCGs. Information of the at least one BSR with flexible length includes the minimum number of the required LCGs, LCG identifiers (LCG IDs) respectively associated with the minimum number of the required LCGs, and at least one buffer area corresponding to the LCG IDs.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
4. The system of claim 1, wherein the service type of the at least one data item to be sent includes at least one of an Ultra Reliable & Low Latency Communication (URLLC) service, a Guaranteed Bit Rate (GBR) service, and a Non-Guaranteed Bit Rate (NGBR) service.
The invention relates to a wireless communication system designed to manage data transmission based on service type requirements. The system addresses the challenge of efficiently handling different types of data traffic in wireless networks, particularly in scenarios where varying levels of reliability, latency, and bandwidth are required. The system categorizes data items into distinct service types, including Ultra Reliable & Low Latency Communication (URLLC) services, Guaranteed Bit Rate (GBR) services, and Non-Guaranteed Bit Rate (NGBR) services. URLLC services prioritize ultra-low latency and high reliability, making them suitable for mission-critical applications such as autonomous vehicles or remote surgery. GBR services ensure a minimum guaranteed data rate, ideal for real-time applications like video streaming. NGBR services do not guarantee a specific bit rate but are optimized for best-effort delivery, commonly used for general internet browsing or email. The system dynamically assigns resources and transmission parameters based on the service type of each data item, ensuring that each type of traffic receives the appropriate level of priority and network resources. This approach enhances overall network efficiency by optimizing resource allocation while meeting the specific quality-of-service (QoS) requirements of different applications. The system may also include mechanisms to monitor network conditions and adjust transmission strategies in real-time to maintain performance across varying service types.
10. The method of claim 7, wherein the service type of the at least one data item to be sent includes at least one of an Ultra Reliable & Low Latency Communication (URLLC) service, a Guaranteed Bit Rate (GBR) service, and a Non-Guaranteed Bit Rate (NGBR) service.
This invention relates to wireless communication systems, specifically methods for managing data transmission based on service type requirements. The problem addressed is the need to efficiently prioritize and transmit data items in a network where different services have varying reliability, latency, and bandwidth demands. The invention provides a method to classify and handle data items according to their service type, ensuring that critical communications are prioritized appropriately. The method involves identifying at least one data item to be sent and determining its service type, which can include Ultra Reliable & Low Latency Communication (URLLC) services, Guaranteed Bit Rate (GBR) services, or Non-Guaranteed Bit Rate (NGBR) services. URLLC services require extremely low latency and high reliability, making them suitable for mission-critical applications like autonomous vehicles or remote surgery. GBR services guarantee a minimum bit rate, ideal for real-time applications such as video streaming. NGBR services do not have strict bit rate guarantees and are typically used for best-effort traffic like web browsing. Once the service type is identified, the method adjusts transmission parameters such as scheduling, resource allocation, or priority handling to meet the specific requirements of the service. This ensures that data items are transmitted in a manner that aligns with their service-level agreements, improving overall network efficiency and user experience. The invention enhances existing wireless communication protocols by dynamically adapting to different service demands, reducing latency for critical services while optimizing resource usage for less demanding traffic.
